Like any good school, (or business), if it's run by a really good CEO/Head Of School (delete inapplicable), that manages the corporate and/or parent communications/interference effectively and runs the school as it should, with good management, proper resourcing, both physical and teaching staff, good structure and discipline, then it would be a good school.
Unfortunately with some Inspired Schools (maybe not all), when the Head of School prior to acquisition leaves the post after the acquisition, Inspired have a reputation if installing one of their "own". One that follows corporate policy at the expense of the school. Our personal experience is that their is little done in the way of staff communication, structure or motivation. The new head of school has been there for 2 years, nearly all the teachers have yet to have a one on one, never attends school staff events, no positive or motivational communication of any sort. In fact most of the communication is based around cutting costs and limiting resources. Motivation is at an all time low amongst the teaching staff.
It has become practice that any school trips that are organised at cost price to parents, Inspired has seen fit to add up to 25% to the cost, for "trip management" (of which the teachers have done everything). In order to get around this, teachers are now asking parents to pay them the cost in cash, and they pay the costs by carrying cash on every outing!! They do this for the benefit of the children and because they actually care.
So yes, maybe there are a few good Inspired Schools, but the Linked In article closely mirrors my wife's experience. So if you're thinking of this group for your kids, just do some homework, you kids education is going to cost you a fortune, make sure you're getting what you expect.
